.Application `filed December 31, 1914. Serial No. 879,964.

T0 au a0/1,0m it may concern.'

Be it known that I, HARRY citizen of the United States, Alliance` J.Hron, a Y residing at i in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Locks, of which thefollowing is a specification.

The invention relates to locks for fire proof cases or cabinets vhavingall the locking parts placed within the case to protect the same fromfire or other elements, and being arranged for locking without the useof a key while requiring a key to unlock them. Such a lock is set forthin my former application, filed June 8, 1914, Serial No. 843,603.

The object of the present improvement is to construct and arrange theparts so that the locking elements located on the separable parts of thecase or cabinet can be engaged for locking by a preliminary operation ofthe lock, while the cabinet parts are adjacent to but not in Contactwith each other; and so that by a further and final 0peration of thelock, the separable rims of the case or cabinet can be drawn, clampedand positively held in sealing Contact with each other.

The general object of the invention, and other attendant advantages, areattained by journaling or swiveling the locking plate on the peripheryof a disk eccentrically secured crosswise on the inner end of theoperating stem, by mounting` the latch upon the eccentric disk andproviding a keeper notch and stops for the latch upon the periphery ofthe locking plate, and by providing stopping means for limiting therotation of the locking plate in opposite directions.

The objects of the invention, thus briey set forth, are attained by thepreferred embodiment thereof illustrated in the accompanying drawings,forming part hereof, in which- Figure 1 is an inner side elevation ofthe lock showing fragmentary parts of the case or cabinet clampedtogether and the locking elements in locked position;

Fig. 2, a section of the same on line 2 2, Fig. 1;

Fig. 3, an elevation similar to Fig. 1, but showing the position of thelocking elements at the end of the preliminary locking operatien;

Fg- 4, a Similar elevation showing the parts throughout the drawings.

The operating elements of the lock may,

include the stem 1, the handles 2, the key cylinder 3, the key 4, theeccentric disk 5; and the locking elements may include the locking plate6, the latch 7, and the locking post `8.

The stem 1 of the lock is provided with the journal 9 on its inner endextending into l and through the corresponding` bearing 10, provided inthe wall 11 of the case or cabinet; and when this wall is made of spacedsurface plates 12, with intervening` heat resisting material 13, asshown, the journal bearing 10 is preferably made in the bushing 14secured between face plates 12 of the wall, which face plates areprovided with apertures corresponding to the journal bearing in thebushing.

The annular shoulder 15 is preferably provided on the stem of the lockin abutment with the outer face ofthe wall, and on the head 16 of thestem are secured the diametrical opposite radial handles 2 which can beconveniently grasped by the hand of the operator for manipulating thelock and opening and closing the case.

The stem 1 is also provided with the axial bore 17, which extends fromthe inner end of the stem outward to a point within the outer endthereof, thus leaving a solid front face 18 for the outer end or head ofthe stem; excepting that the slot 19 is provided therein for theentrance of the wings 2O of the key 4, which slot is preferably providedwith a central enlargement 21 for the shank 22y of the key.

The key cylinder 3 is fitted neatly in the bore of the stein, and isprovided in its outer end with the diainetric slot 23 having the centralenlargement 24 for receiving the Wings 20 and the shank 22 of the key;and on its inner end with the diametric tongue 25 protruding inwardbeyond the inner end of the stem.

The operating disk 5 is eccentrically secured on the inner end of theoperating stein as by means oi' the screw threaded shank 26 on the innerend or' the stem entered in the 'corresponding aperture 27 in the diskand .held thereon by the nut 26 screwed upon the shank; the shank andthe aperture being iiattened on one side to stop a rotation of the diskwith reference to the stein.

The peripheral flange 28 extends outward from one side oit the peripheryof the disk, in which flange is provided the diametrically oppositeguide-Ways 29 which receive and guide the latch 7 in its endivisemovements, which latch is diametrically located on the inner side of theeccentric disk.

The latch 7 is slidably retained by the cap screw 30, having its shankextended through the longitudinal slot 3l ifoiined in the latch, andscrewed into the body of the disk. The latch ispalso provided with thecam orifice 32 which receives the diametric tongue 25 on theV inner endot the key cylinder; the edges ot which tongue operate against thesquared end 34 ot the orifice 'for moving the latch in one direction, asshown in Fig. 4, and the ilat sides of the tongue may abut the saine endot the oriiice and may stop its movement in the opposite direction asshown in Figs. l and 2. The spring 35 is also provided iii bearingengageinent with the latch and the disk so as to move the same in theopposite direction from its operation by the cylinder tongue, for thelocking operation of the latch.

The locking `plate 6 is rotatably mounted or journaled on the eccentricdisk so that it fits neatly around the entire periphery and has aportion 36 oi' its periphery circulaily formed concentric with thecenter of the disk, over which peripheral portion of the locking platevthe lateral tongue 37 on one `end of the latch extends when the same isin its unlocked position as shown in Figs. 3, 4 and 5; and While in thisposition the spring 35 acts to draw the tongue inward until it isstopped by a sliding engagement with the periphery of the locking plateWhenever the key cylinder is turned to bring the tongue 25 on its innerend transverse the latch, jas shown in Figs. 3 and 5, which is ltheposition vto, which the cylinder must be turned to Withdraw lthe keyfrom the stein o the lock.

The stop 38 is provided at one end of the stop slide portion 36 of thelocking plate, for 'stopping the 'relative rotary movement of the latchand the operating disk with reference to the locking plate in onedirection; and the keeper notch 39 is provided in the periphery or' thelocking plate at the other ,end of the stop slide portion 36 thereof,

into which notch the tongue of the latch is adapted to enter and be held'for holding vkand securing the operating and locking elements in lockedposition, as shown in Fig. 2; the entrance oi the tongue into the notchbeing eliected by the' action of the locking spring 35, Whenever thetongue of the latch is rotated to register with the notch.

To prevent a binding of the latch tongue against the-sides 40 and 40a ofthe keeper notch, the stop pin 41 is preferably provided on the side ofthe locking plate in the path of the lug 42 on the periphery of theeccentric disk; which lug is adapted to impinge and be stopped by thepin after the latch tongue clears the one -side 40 oit the keeper notchand before it impinges the other side 40"L thereof, as shown in Fig. l.It will be understood, however', that the use ot theseparate stop pin 41is not essential7 for in lieu thereof, the side 40 of the keeper notchmay be extended, as shown, and Will serve as a stop for the latchtongue, to pre vent its moving beyond the keeper notch.

The stop post 43 is provided on the inner side of the Wall l11 oi' lthecase or cabinet, for limiting the rotation of the locking plate inopposite directions. This post preferably protrudes into the slottedaperture 44 provided in the locking plate, one end 46 ot which 'slotforms an abutment for liin iting the rotation of the locking plate inone direction in' its normal unlocked position, as shown in Fig. 4; andthe other end 4Gn forms an abutment for stopping the r0- tation of thelocking plate in the opposite direction in an abnormal unlockedposition, as shown in Fig. 5.

And finally, the hook 47 is provided on the extended end 4S of thelocking preferably diametrically opposite from the keeper notch 89 inthe periphery thereof, which hook is adapted to engage and cooperateivith the locking post 8 secured on theinner side of 'the Wall 11a, tothe rim of Which Wall the rim Aof the wall 11 is designed to be clampedand locked.

The locked relation of the parts is shown in Figs. 1 and 2, with thelateral tongue 37 of the latch engaged in the keeper notch 39 iii theperiphery of vthe locking plate. In' this relation of the parts, it isevident that by inserting the Wings of the key through the slot 18 inthe stem into the slot 23 in the key cylinder, the cylinder can berotated by the key so that the tongue 25 on its inner end Will move thelatch longitudinally, against the action of the lock plate, 1

in the periphery of the locking plate. After the latch tongue is thusdisengaged, the ecw centric disk may be rotated by the stem and thehandles, and the tongue of the latch will pass over and along' the stopslide portion 36 of the locking plate, as shown in Fig. 4.

The hook 47 being' engaged with the locking post S, the first portion ofthis rotation swings the upper end of the locking plate to the right, asthe lock is illustrated, by the rotation of the eccentric disk in thelocking plate; and the turning of the eccentric disk in the lockingplate carries the lateral tongue of the latch from above the keepernotch, over and along the stop slide por tion 36 of the locking plate,and also moves the locking plate downward until the end of the hook 47is disengaged from the locking post, as shown, approximately, in Fig. 3.

If the key is permitted to remain in the lock with the tongue 25 on thekey cylinder holding the latch tongue free of the stop slide, during thefurther rotation of the eccentric disk, and after the hook 47 isdisengaged from the locking post, the locking plate may hang withoutrotation on the eccentric disk, until the latch tongue strikes the stop38 on the locking plate, as shown, approximately, in Fig. 3; after whichthis plate is rotated with the eccentric disk to carry the hook 47 clearbeyond the side of the locking post 8, and the turning may continueuntil further rotation is stopped by contact of the end 46 of theaperture 44 with the stop post 43 on the wall of the case, as shown inFig. 4.

When, however, the key is turned for removing from the stem, whichturning rotates the cylinder tongue crosswise and permits the latchtongue to press against the stop slide by action of the locking spring;or when the swivel bearing of the locking plate upon the eccentric diskis fitted closely enough to irictionally engage these parts; the lockingplate may begin to rotate with the eccentric disk, just as soon as thehook thereon is disengaged from the locking post, and may continuerotating until the plate is stopped by the post 43; after which thelatch tongue will slide upon the stop slide and the eccentric disk willslide within the swivel bearing of the locking plate, until the latchtongue impinges the stop 33 onv the locking plate, as shown in Fig. 4,which prevents turther movement of the locking elements. In thisrelation of the parts, which is ret'erred to herein as the normalunlocked position of the lock, the handles of the stem are preferablylocated in horizontal position so that they can be readily grasped forraising and lowering the upper portion of the case or cabinet on whichthey are mounted.

For rengaging the hook of the locking plate with the locking post, anddrawing.l clamping and locking the separable parts ott the case orcabinet together; the stem otl the lock is first rotated by its handlesin the reverse direction, until the shank 49 ot the hook impinges theside of the locking post S, with the hook immediately below the post, asshown in Fig. 3; and as shown, this operation may be made when the rimsoi2 the case or cabinet parts are spaced apart at a substantial intervalfrom each other.

In event the key has been rotated to rc move it from the stem, so thatthe cylinder tongue has been turned crosswise and the latch tongue isdrawn against the stop slide by action of the locking spring, as shownin Fig. 3; it is evident that the locking plate will be rotated more orless positively into this position by the turning of the eccentric disk,and the rictional engagement ot the latch tongue with the stop slide;and even though the key is not turned for removal :from the stem, andthe latch tongue is held free from the stop slide as shown in Fig. 4,the irictional engagement in the swivel bearing on the latch plate onthe eccentric disk, or the mere weight of the hooked end of the lockingplate, serves to carry the hook laterally from the position shown inFig. 4 to the position shown in Fig. 3, when the eccentric disk andlatch are rotated to the position shown in the latter gure.

lVhen the parts of the lock are in this position, it is vident that afurther rotation ot the eccentric disk in the same direction will causethe latch tongue to slide upon or move freely along the stop slide 36,depending upon the position oi" the key cylinder; and the turning of theeccentric disk in the swivel bearing of the locking plate, carries thesame upward so that its hook will first engage and then draw the lockingpost to clamp the rims of the separable parts of the case or cabinettogether. The parts are so arranged that when this is accomplished, thetongue of the latch will have moved directly above the keeper notch,into which the tongue is drawn by action of the locking spring, as shownin Fig. 2; the stop pin 4l on the locking plate and the stop shoulder 42on the eccentric disk being arranged to stop the parts in properposition so that the latch tongue will freely enter the keeper notchwithout rubbing against either side thereof.

To prevent such a turning of the partel iu the reverse direction as willpermit a locking oi the latch tongue in the keeper notch, when the hookis disengaged 'from the locking post. when the case or cabinet is openedas shown in Fig. the contact ot the end 46 of the slot 45 against thepin 43 servos to stop the rotation ot the eccentric disk and the lockingplate in the reverse direction,

before the latch. tongue is rotated iar enough to enter the keepernotch; the stopping of the disk and latch being accomplished by therelative positions of the center of the eccentric disk and swivelbearing with reference to the center oiA the locking stem, whichprevents a further turning of the disk in its sivivel bearing after thelocking plate is stopped to prevent a i'urther downward and lateralmovement of the center ot the eccentric disk toward the stop pin A3.
